Tasman Island Survey
In November 2005 a team of six scientists including two New Zealand volunteers conducted a seven-day integrated biological survey. A range of field techniques were used to investigate various aspects of the island's ecology including vegetation quadrat surveys and weed mapping, vertebrate and invertebrate sampling, spotlighting and pest control measures. Six vegetation communities were intensively ground-truthed and used as the basis for fauna sampling and a study of vegetation composition.
- Eight previously unrecorded native flora taxa were found on the island.
- Observations were made on the newly discovered breeding group of New Zealand Fur Seals.
- Nine species of land snail were collected adding to the previously one known species. A new "Tasman Island" species has been discovered
- Twenty six species of land and seabirds were recorded including breeding records and the positive identification of Lewin's Rail.
- The local extinction of the Little Penguin colony was confirmed.
